Warning: Beware of fake telephones and electronics.

When it comes to buying smartphones and other mobile devices on the internet, especially from the Far East, the old warning "Let the buyer beware" is definitely worth heeding. Fake Apple, Nokia and Samsung products are sold massively worldwide, with new copies emerging almost as soon as the genuine items are unveiled.

While it may not be surprising that devices sold on the African streets at a tremendous "bargain" are usually fakes, they are also sometimes sold in supposedly respectable establishments in malls and shopping centers alongside authentic products.

Generally the vendors themselves acknowledge they are selling copies, as they are so much cheaper. When you ask to see a particular model, many sellers reply: Do you want a genuine or a fake? Some even offer a warranty for the fakes for a short period of time, promising to exchange the set if it breaks down. Of course, the sincerity of this promise can only be verified by making a purchase; it may often be just a gimmick to make the sale, with no intention of delivering.

Authorities in Africa said that of all the other fake products sold on the continent, including watches, handbags, leather goods and other fashionable items, mobile IT products are at this moment enjoying the most popularity.

Extra alerts also on batteries and chargers.

It is also reported that fake batteries can be dangerous. Official replacement batteries can be expensive. Whether you are looking at a laptop or smartphone battery, you may be tempted to take the cheap route and buy an aftermarket battery. But this decision could blow up in your face literally.

Aftermarket batteries made by other manufacturers can often be found for significantly cheaper. In reality , they are not worth the savings. Cheap aftermarket batteries could catch fire, explode, and even burn down your house or physically injure you. The same problem is mentioned for cheap chargers. It can seriously damage your phone and even spoil your warranty.
